An Australian Audit Of Vaccination Status In Children And Adolescents With Inflammatory Bowel Disease

Table 2. Baseline Characteristics One hundred and one hospital patient records were reviewed as detailed in the study flow diagram. (Figure 1 ) A telephone immunization survey was completed in 42% and primary care practitioner records obtained in 66% (33/50) of consenting participants. In those whom a complete telephone immunization survey was obtained, 90% (38/42) [95% confidence intervals (CI) 77%; 97%] were up-to date with routine primary childhood immunizations. Figure 1. Flow diagram of study participants. For additional recommended vaccines, only 5% (5/101) [95% CI 2%; 11%] had received a recommended pneumococcal ‘booster’ and all were on active therapy including azathioprine (4) and infliximab (1). 10% (10/101) [95% CI 5%; 17%] had evidence of having ever received an influenza vaccination, 7% (7/101) [95% CI 3%; 14%] in the year of the survey. Those living in rural Victoria (Odds ratio 6.51 95% CI 1.33; 41.25, p = 0.005) and younger at the age of diagnosis (Pearson square for trend 2 = 16.8; p = 0.002) were more likely to have received an influenza vaccine. The reasons for not having received an influenza vaccine (n = 33) included: not being aware of it (24%); concerned about side effects (24%) not necessary (15%); doctor did not offer it (6%), allergy (6%) and unspecified or other reason (25%). Serological testing, reviewing historical protection from VPD, identified 18% (17/94) with evidence of at least one serology sample.
